CAPM Practice: Demonstrate an understanding of a project management plan schedule

Schedule reserve (contingency reserve) is time added to the schedule to address identified risks and schedule uncertainty. It is part of the schedule baseline and is managed by the project manager. Management reserve is additional time held by management for unforeseeable risks, above and beyond the contingency reserve.

**Why not A:** Management reserve is additional time or budget held by management for unforeseeable risks (unknown unknowns). It is separate from the schedule baseline and is not managed by the project manager, unlike schedule contingency reserve which addresses identified risks.

**Why not B:** Float allocation is not a recognized project management term for time buffers. Float (or slack) is the amount of time an activity can be delayed without affecting the project end date, and it is a property of individual activities in the network, not an added buffer.

**Why not D:** Sprint buffer is not a standard predictive project management term. Sprints are associated with agile methodologies, and the concept of adding buffers at the end of a project to protect against schedule uncertainty is specific to predictive scheduling approaches.
